p This invention relates to metal cutting tools or implements, and moreparticularly to a shears for cutting bar iron of either round or angularconfiguration, springs, and galvanized iron and tin. i

An object of this invention is to provide a tool for generalblacksmithing, garages, automobile spring works, tin shops or the likewhich will save a considerable amount of time incutting of metal, suchas plow points, spring harrow teeth, or the like, and which is quick inaction on either hot orcold metal and thereby eliminates the usualhelper while performing the work in a man ner so that no ragged edgeswill be left.

Another object of this invention is to provide in a device of this kindmeans which maybe mounted on an anvil, bench or the like, bywhich themovable blade or cutter may be readily swung into open position withoutmanually touching the blade.

A further object of this invention is to provide a cutter or shears ofthis kind which is so constructed that it will stay in desired positioneither open or closed, so that the article to" be cut may be held in onehand and the lever or sledge operated with the other hand, so as to cutthe article at the O desired point.

The above and various other objects and advantages of this inventionwill in part be described in and in part be understood from thefollowing detailed description of the present preferred embodiment, thesame being illustrated in the accompanying drawing, wherein:

Figure 1 vis a detail side elevation partly .s in section of a deviceconstructed according to the preferred embodiment of this invention,showing in dotted line the open position and in full line the closedposition of the device;

Figure 2 is a top plan view of the device partly in section, and

Figure 3 is a sectional view taken on the line 3-8 of Figure 1. 7

Referring to the drawing wherein like numerals of reference designatecorresponding parts throughout the several views, the

numerallO designates generally a stationary blade of a cutter or shearsconstructed accordingto the preferredembodiment of this invention whichhas a straight cutting edge 11 on the upper edgethereof, and the numeral12 designates a pivotedor movable lade which is pivotally. mounted onthe stationary blade adjacentone edge thereof by means of a pivotalmember 14; in the form of a bolt or the like which extends through thestationary bladelO and the Inov+ able blade12. Y

. The upperkeen edge 11 of the stationary blade 10 is provided with acurved cutting portion 13 intermediate the ends thereof and inlikeinanner, the keen edge 15 of the movable blade ,12 ,is provided witha comple mentary curved cutting portion 16 which is disposed oppositelyfrom the cutting por- 1 tion 13 so that a round article in the form of abar or the like may be readily inserted within the curved cuttingportion 13 and the bar cut olf by engagement of the cutting portion 16with the bar. These curved cutting portions prevent sliding movement ofthe bar with respect to the two blades as the movable blade 12 is movedtoward the fixed blade 10. The movable blade 12 has an upwardlyextending handle or releasing member 17 formed therewith and disposed atone end of the blade 12, this handle 17 being preferably disposedadjacent the pivoted end of this blade. The bolt 14 ispreferably'elongated and a spring 18 isdisposed 7 thereabout and heldresiliently against the outer face of the movable blade 12 by means of atensioning nut 19 so that the movable blade 12 will be resiliently heldinto engagement with the fixed blade 10. The movable blade 12 isprovided with an outstanding pin or stud 20 adjacent the free endthereof, which pin 20 is adapted to be engaged by a manually operatedlever, generally designated as 21. This lever 21 (T has an enlargedinner end portion 22 provided with an opening or aperture 23therethrough within which the bolt 14, together with the nut 19 and thespring 18 is adapted to bedisposed and intermediate the ends of thislever 21, there is also provided a second i enlarged portion 24 havingan aperture 25 therethrough within which the stud or pin 20 is removablydisposed so that the pivot 14 will not only act as a fulcrum for themovable blade 12, but also as a fulcrum for the operating handle orlever 21.

In order to support the shears comprising the fixed blade 10 and themovable blade 12 in the desired position, I have provided a shank orstud 26 which has a plate 27 formed with the upper end thereof, whichplate 27 is secured to the fixed blade 10 by means of bolts or rivets 28or the like. This shank 26 is adapted to be positioned in the hardy holeof an anvil or the like, and is of a configuration to removably engagein this hardy hole or any other desired aperture of a'supporting member.In order to properly support or mount the shears on a bench orthe like,a socket member 29 having an upper flange 80 may be mounted in thedesired opening in the bench or other support and the opening or passage31 in the socket 29 of a size to removably receive the shank 26.

In the operation of this device, the shank '26 may be mounted in a hardyhole of an anvil or in the socket 29, which is mounted in a hole in abench or the like, and the movable blade 12 swung upwardly either byforcing the handle 17 downwardly or by taking the lever 21 and mountingthis lever 21 on the pivot 14 so that it will engage the pin 2O. Thedesired article may then be disposed between the two cutting blades andthe upper edge of the movable blade 12 struck with a hammer or sledgeprovided the article is'of a relatively heavy nature so that the movableblade 12 cannot'be readily closed by operating the lever 21.

lVhen the article has been cut off, the movable blade may again beopened by striking the handle 17 with the hammeror and rocked downwardlyso as to close the blades. A

It will be obvious, from the foregoing, that the shears or cutter hereindisclosed may be readily operated to cut articles which are heated toiarelatively high degree such as vehicle springs, bars, plates or thelike, and that if the article is not of a relatively small nature, theshears may be readily operated without touching the movable blade withthe hand. I

It is, of course, understood that various changes and modifications maybe made in the details of construction "and design of the abovespecifically described embodiment of this invention without departingfrom the spirit thereof, such changes and modifications being restrictedonly by the scope of the followingclaim.

I claim A metal shears of the character described comprising a pair ofblade members, means for *pivota'lly and 'yieldably securing said blademembers together,-a shank, means for securing said shank to 'oneof saidblades intermediate the ends thereof, an -outstanding pincarried by theother of said "blades, and'a handle looselyand removably engaging saidpivot meansand said pin whereby to rock said other-blade onsaid pivotmeans,

said handle includingan elongated bar having a pairo'f'eyesspacedapart'and engageable with the pivot means and the pin.
